- - A new incremental-recursion algorithm is now used when rsync is talking
- to another 3.x version. This starts the transfer going more quickly
- (before all the files have been found), and requires much less memory.
- See the --recursive option in the manpage for some restrictions.
-
- - Lowered memory use in the non-incremental-recursion algorithm for typical
- option values (usually saving from 21-29 bytes per file).
-
- - The default --delete algorithm is now --delete-during when talking to a
- 3.x rsync. This is a faster scan than using --delete-before (which is
- the default when talking to older rsync versions), and is compatible with
- the new incremental recursion mode.
-
- - Rsync now allows multiple remote-source args to be specified rather than
- having to rely on a special space-splitting side-effect of the remote-
- shell. Additional remote args must specify the same host or an empty one
- (e.g. empty: :file1 or ::module/file2). This means that local use of
- brace expansion now works: rsync -av host:dir/{f1,f2} .
-
- - Added the --protect-args (-s) option, that tells rsync to send most of
- the command-line args at the start of the transfer rather than as args
- to the remote-shell command. This protects them from space-splitting,
- and only interprets basic wildcard special shell characters (*?[).
-
- - Added the --delete-delay option, which is a more efficient way to delete
- files at the end of the transfer without needing a separate delete pass.
-
- - Added the --acls (-A) option to preserve Access Control Lists. This is
- an improved version of the prior patch that was available, and it even
- supports OS X ACLs. If you need to have backward compatibility with old,
- acl-patched versions of rsync, apply the acls.diff file from the patches
- dir.
-
- - Added the --xattrs (-X) option to preserver extended attributes. This is
- an improved version of the prior patch that was available, and it even
- supports OS X xattrs (which includes their resource fork data). If you
- need to have backward compatibility with old, xattr-patched versions of
- rsync, apply the xattrs.diff file from the patches dir.
-
- - Added the --fake-super option that allows a non-super user to preserve
- all attributes of a file by using a special extended-attribute idiom.
- It even supports the storing of foreign ACL data on your backup server.
- There is also an analogous "fake super" option for an rsync daemon.
-
- - Added the --iconv option, which allows rsync to convert filenames from
- one character-set to another during the transfer. The default is to make
- this feature available as long as your system has iconv_open(). If
- compilation fails, specify --disable-iconv to configure, and then
- rebuild. If you want rsync to perform character-set conversions by
- default, you can specify --enable-iconv=CONVERT_STRING with the default
- value for the --iconv option that you wish to use. For example,
- "--enable-iconv=." is a good choice. See the rsync manpage for an
- explanation of the --iconv option's settings.
-
- - Added the --skip-compress=LIST option to override the default list of
- file suffixes that will not be compressed when using --compress.
-
- - The daemon's default for "dont compress" was extended to include:
- *.7z *.mp[34] *.mov *.avi *.ogg *.jpg *.jpeg
- The matching routine was also optimized to run more quickly.
-
- - The --max-delete option now outputs a warning if it skipped any file
- deletions, including a count of how many deletions were skipped. (Older
- versions just silently stopped deleting things.)
-
- - You may specify --max-delete=0 to a 3.0.0 client to request that it warn
- about extraneous files without deleting anything. If you're not sure
- what version the client is, you can use the less-obvious --max-delete=-1,
- as both old and new versions will treat that as the same request (though
- older versions don't warn).
-
- - The --hard-link option now uses less memory on both the sending and
- receiving side for all protocol versions. For protocol 30, the use of a
- hashtable on the sending side allows us to more efficiently convey to the
- receiver what files are linked together. This reduces the amount of data
- sent over the socket by a considerable margin (rather than adding more
- data), and limits the in-memory storage of the device+inode information
- to just the sending side for the new protocol 30, or to the receiving
- side when speaking an older protocol (note that older rsync versions kept
- the device+inode information on both sides).
-
- - The filter rules now support a perishable ("p") modifier that marks rules
- that should not have an effect in a directory that is being deleted. e.g.
- -f '-p .svn/' would only affect "live" .svn directories.
-
- - Rsync checks all the alternate-destination args for validity (e.g.
- --link-dest). This lets the user know when they specified a directory
- that does not exist.
-
- - If we get an error setting the time on a symlink, we don't complain about
- it anymore (since some operating systems don't support that, and it's not
- that important).
-
- - Protocol 30 now uses MD5 checksums instead of MD4.
-
- - Changed the --append option to not checksum the existing data in the
- destination file, which speeds up file appending.
-
- - Added the --append-verify option, which works like the older --append
- option (verifying the existing data in the destination file). For
- compatibility with older rsync versions, any use of --append that is
- talking protocol 29 or older will revert to the --append-verify method.
-
- - Added the --contimeout=SECONDS option that lets the user specify a
- connection timeout for rsync daemon access.
-
- - Documented and extended the support for the RSYNC_CONNECT_PROG variable
- that can be used to enhance the client side of a daemon connection.
-
- - Improved the dashes and double-quotes in the nroff manpage output.
-
- - We now support a lot more --no-OPTION override options.
